QUALITY OF WELD CLADS APPLIED BY SAW METHOD IN ADHESIVE WEAR CONDITIONS
Journal Title: Materials Engineering - Materialove inzinierstvo (MEMI) - Year 2013, Vol 20, Issue 1
Abstract
This contribution deals with the analysis of the renovation layer quality of continuous casting steel rolls, developed through the submerged arc surfacing method (SAW). The continuous casting roll was analysed via the degradation phenomena which act during the operation. Four kinds of filler materials were used for the renovation of the worn roll. Surfacing was carried out as a three-layer in order to eliminate the need for intermediate layer formation. The quality of weld deposits was evaluated in terms of the structure, hardness and wear resistance of weld deposits at 23°C and 400 °C using pin-on-disc wear test. The best properties showed newly developed filler material W8-WLDC8 from the point of view of the hardness, together with wear resistance of the deposited layers in room and elevated temperatures.
